South Plaza and Santa Fe Island are two Small Island off the coast off Santa Cruz, each one of them with its own kind of land iguana. South Plaza however it is overpopulated with land iguanas because they lost its top predator, the Galapagos hawk, The Galapagos National Park it is working in order to restore this island otherwise in the near future they are going to cause their own extortion on the island.
Santa Fe on the other hand look very healthy. That is when the Island has a harmonious ecosystem with top predators as the stewards of the Galapagos Islands.
